Important !
The "SRS" airbags are designed to activate only in certain frontal or rear (front airbags) impacts, or side (side
airbags) impacts. Only during these types of impacts, if of sufficient severity to meet the deployment
thresholds, will they provide their supplemental protection. The driver and passenger should always wear the
seat belts, otherwise it is not possible for the airbags to provide their intended supplemental protection. In
cases of other frontal impacts, angled impacts, roll-overs, other side impacts, rear collisions, or other
accidents without sufficient forces, the airbag will not be activated. The driver and passengers will then be
protected by the fastened seat belts. We caution you not to rely on the presence of an airbag in order to
avoid wearing your seat belt. The "SRS" is designed to reduce the potential of injury in certain frontal and
rear (front airbags) impacts, and side (side airbags) impacts which may cause significant injuries, however,
no system available today can totall y eliminate injuries and fatalities.
The activation of the "SRS" temporarily releases a small amount of dust from the airbags. This dust,
however, is neither injurious to your health, nor does it indicate a fire in the vehicle. The service life of the
airbags extends to the date indicated on the label located on the driverside door latch post. To provide
continued reliability after that date, they should be inspected by an authorized Mer cedes-Benz dealer at that
time and replaced when necessary.


Warning!
It is very important for your safety to always be in a properly seated position and to wear your seat belt.
For maximum protection in the event of a collision always be in normal seated position with your back
against
the seat back. Fasten your seat belt and ensure that it is properly positioned on the body. Since the airbag
inflates with considerable speed and force, a proper seating and hands on steering wheel position will help
to keep you in a safe distance from the airbag:
• Sit properly belted in an upright position with your back against the seat back.
• Adjust the driver seat as far as possible rearward , still permitting proper operation of vehicle controls.
• Do not lean with your head or chest close to the steering wheel or dashboard.
• Keep hands on the outside of steering wheel rim. Placing hands and arms inside the rim can increase the
risk and potential severity of hand/arm injury when airbag inflates.
• Adjust the front passenger seat rearward as far as possible from the dashboard when the seat is occupied.
• Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates
with the BabySmart™ system installed in the vehicle to deactivate the passenger side front airbag when it
is properly installed. Otherwise they will be struck by the airbag when it inflates in a crash.
If this happens, serious or fatal injury will result . Failure to follow these instructions can result in severe
injuries to you or other occupants.

Safety Guidelines for the Seat Belt, Emergency Tensioning Retractor and Airbag


Warning !

• Damaged belts or belts that were highly stressed in an accident must be replaced and their anchoring
points must also be checked. Use only belts installed or supplied by an authorized Mercedes-Benz dealer.
• Do not pass belts over sharp edges.
• Do not make any modification that could change the effectiveness of the belts.
• The "SRS" is designed to function on a one-time-only b asis. An airbag or emergency tensioning retractor
(ETR) that was activated must be replaced.
• No modifications of any kind may be made to any components or wiring of the "SRS". This includes
the installation of additional trim material, ba dges etc. over the steering wheel hub, front passenger
airbag cover, or front door trim panels, and in stallation of additional electrical/electronic equipment on
or near "SRS" components and wiring.
• An airbag system component within the steering wheel gets hot
after the airbag has inflated.
• Improper work on the system, including incorrect
installation and removal, can lead to possible injury
through an uncontrolled activation of the "SRS".
• In addition, through improper work there is the risk of rendering the "SRS" inoperative. Work on the
"SRS" must therefore only be performed by an authorized Mercedes-Benz dealer

When you sell the vehicle we strongly urge you to give notice to the subsequent owner that it is equipped with an
"SRS" by alerting him to the applicable section in the Owner's Manual.

Night Security Illumination

approximately 30 seconds after closing the last door. The lamp-on time period can be changed at your
Mercedes-Benz dealer.
